Shaft Nut Penske Bump Stop 7150

The RE Suspension Shaft Nut Penske Bump Stop 7150 is a precision steel fastener engineered to secure shock shaft assemblies on Penske aftermarket suspension systems. This critical component maintains proper preload on bump stop assemblies, preventing unwanted movement and ensuring consistent shock performance during suspension compression events. The natural steel finish provides corrosion resistance suitable for extended off-road or high-performance driving applications where suspension integrity is non-negotiable.

Manufactured by RE Suspension as an OEM-specification replacement, this shaft nut (part number RE-BR-NT7150) matches factory tolerances required for Penske shock systems. The compact 1.55 x 0.4 x 2.85-inch profile and minimal 0.09 lb weight ensure zero performance compromise while delivering robust clamping force to the shock's internal shaft assembly. Proper torque application during installation is essential—this nut secures the bump stop washer and locates the elastomer stack at the correct compression depth, directly affecting the shock's bottoming characteristics and ride harshness on track or trail.

This fastener is ideal for suspension technicians, off-road builders, and track competitors performing maintenance or rebuilds on Penske-equipped vehicles. Whether replacing a stripped or corroded nut during shock service, upgrading to fresh OEM hardware, or rebuilding a suspension system after hard use, the Penske Bump Stop 7150 shaft nut ensures correct assembly and reliable long-term performance. Each nut is sold individually, allowing buyers to source exact replacements without purchasing unnecessary hardware packs.
